This Fusarium oxysporum f. sp. matthiolae strain PHW726 genome was assembled and published by Yu et. al. (2020) and deposited in the NCBI database. The JGI Fungal Annotation Pipeline was used to predict gene models and provide functional annotation.

Fusarium oxysporum, an ascomycete fungus in the Nectriaceae family, is predominant in native soils. While some species may be harmless or even beneficial plant endophytes or soil saprophytes, many strains within the F. oxysporum species complex are pathogenic to plants, especially in agricultural settings. F. oxysporum f. sp. matthiolae strain PHW726 is one of three formae speciales that are pathogenic to crucifers, including Arabidopsis thaliana, a premier model for plant molecular biology and genetics. The genome sequence of F. oxysporum forma specialis matthiolae strain PHW726 will enable the genetic analysis of fungal pathogenesis and host immunity using the model plant Arabidopsis thaliana.
